To all whom it may concern:

Be it known that I, GEORGE H. SMITH, of New Yori@ in the county of NewYork and State of New York, haveinvented certain new 'Send usefulImprovements in Methods of and Apparatus for Making and RaisingSalt-Brine from Deep Veins and I do hereby declare that the followingis a full, clear, and erect description of the invention, such as willenable others skilled in the'art towhich it-appertains to make and usethe same, reference being' had to the accompanying drawings, which Yformapart of this specification;` i My invention relates to a method of andsame from deep wells or veins in salt deposits, and is hereinafterdescribed and claimed.

A stratum of solidsalt of from forty to seventy feet in thicknesshas'been discovered in the eonnty of Wyoming, State of New York, at a. depthof one thousand feet and more' yfrom the surface. Owing to the depth andVprooebie'- cost of drainage, itV is not thought desirable to mine thissalt by shafts and drifts. 25 Salt has-been obtained in considerablequan- Y Y`cities by pumping water into wells reaching down `to lthisdeposit, and then pumping it ontv ngain'in theA form'of brine. AWater-supply ffrom outside the wells has been found to bel3o*necessary-o1' advantageous, owing to lack of sucient water at thisgreet depth, eindv also -because the water supplied to .the wells can bekept pure and free from ingredients which might be deleterious to thesalt, which might ter were reliedon to ill the wells and dissolve"thesaln 1 I havel invented a method. by which deepwell pumping may bedispeusedwith, all the 4o machinery except the pipes be above ground,and the brine can be obtained more cheaply then has-heretofore beendone. My method is now in use ata. well some fourteenhnndred e feet indepthin' the town of Middlebury, New 4 5 York, and gives excellentresults. The brine,

after `being forced out of the well, is evaporated,vaud salt formed inthe usual manner.

The apparatusby which my method is carried out is illustrated in theaccompanying drawings, but is subject to modification within the spiritof the invention.

In the drawings, Figure is e sideelevea tion,`pertly in section, of oneform efmy apparatusfin position in a well. Figs. 2 and 3. aremodifications, the general principles ofrop- 55 eration being the same.f A represents e deep well, in vvwhich a casing, A', is placed, whichextends down below the vfresh-witter veins,- esie usuel in oibwells, atwhich pointtbe caf-sing is tightly packed with 6o suitable pecking, @toexclude all drainage from the weil, end also to permit the applice- Ytion of pressure from below to expel the brine'. The casing Atmeycr maynot'fo'rm one of the tubes or pipes by which the brine is expelled 6 5from the well. j v v B is a supply-pipe, which may be the casing of theweiber mey bee separate pipe, as shown. Through this pipe water isforced inte the well by eey suit-chie menus, end by. 7o its presscrelforces ont' the water 'which has preceded it inthe weil, enti whichlhas become saturated with seit yby contact with the deposit of salt. 'inFig. the inner pipe is the pressure-pipe, while the casing A' serves esthe 7g conduit for tbebrine. v

D is e forcepump,.by which water is forced intothe well, while Eis estand'pipe counected'with the supplypipe and serves to give a steadypressure; but this stand-pipe may be 8c Y omitted.

In Fig. 3 have shown e wel! in which the casing is dispensed with; bute-paeking n. is used, through which the pressure-pipe B and supply-pipeC pass., In this form einpressnre 85 may be used to force up brine, thewater bavin'g been rst introduced into the well to ebsorb the salt.

It is obvious that the pump may be dispensed with vwhere there is e.natura-l heed er 9o pressure of water above the mouth of tbe well, eswhere` water een be obtained from weterwcrks, es is the cese in Varsaw,New York.

I am were that it -is :not broadly new to 95 raise oil and other liquidsfrom deep wells by heudrsniic or pneumatic pressure; and l do notbroadly cla-im such devices.

Wirst I claim is- The method of obtaining brine from salt roo weils,which consists in forcing fresh water into the well under pressure,permitting it to absorb salt by Contact with the undergrour'ldv deposit,and then expelling'the same from the 'well bythe pressure of a column of"water or.
